Preface
Intended Audience
This manual is written for the system manager or system operator who
has had training in system management tasks and is running a DEC 7000
or a VAX 7000 system.

Document Structure
This manual uses a structured documentation design. Topics are organized into small sections for efficient on-line and printed reference. Each
topic begins with an abstract. You can quickly gain a comprehensive overview by reading only the abstracts. Next is an illustration or example,
which also provides quick reference. Last in the structure are descriptive
text and syntax definitions.
This manual has three chapters and one appendix as follows:
•

Chapter 1, System Troubleshooting, tells you what to do if something goes wrong.

•

Chapter 2, Self-Test, explains how to interpret the self-test display.

•

Chapter 3, Getting System Information, explains how to identify
the modules and devices in your system and how to test them.

•

Appendix A describes the indicators on the various power system
components.

Conventions Used in This Document
Terminology. Unless specified otherwise, the use of "system" refers to
either a DEC 7000 AXP or VAX 7000 system. The DEC 7000 AXP systems
use the Alpha AXP architecture. References in text use DEC 7000 to refer
to DEC 7000 AXP systems.
When a discussion applies to only one system, an icon is used to highlight
that system. Otherwise, the discussion applies to both systems. Thus, the
abstract for a module that applies only to DEC 7000 systems would look
like this:
This section shows a sample boot of OpenVMS Alpha AXP
DEC from the RRD42 CD drive for DEC 7000 systems. The first
7000
step is issuing the show device command to determine the
location of the RRD42.
Book titles. In text, if a book is cited without a product name, that book is
part of the hardware documentation. It is listed in Table 1 along with its
order number.
Icons. The icons shown below are used in illustrations for designating part
placement in the system described. A shaded area in the icon shows the
location of the component or part being discussed.

1.8 Air Pressure Sensor and Temperature Sensors
An air pressure sensor is located on the cabinet control logic
(CCL) module and is connected to the LSB card cage by a tube. If
the sensor detects a pressure differential, then the system power
regulators are disabled.

Figure 1-10

CCL Air Pressure Sensor

Front

Air Pressure
Sensor
BXB-0044A-92

The air pressure sensor monitors the pressure differential across the upper cabinet. If the air pressure drops below normal, all system power
regulators are disabled and the control panel Fault light will blink.
CAUTION: Do not place any materials on top of the cabinet. Doing so
may cause your system to shut down.
The system also has temperature sensors located on the system power
regulators, the disk converter module, the PIU power regulators, and the
CCL module.

2-2 Self-Test

Following power-up and system reset, the system performs testing. Selftest results are indicated by the following:
•

Fault light on the control panel

•

Self-test LEDs on the modules

•

Self-test display

The self-test display is discussed in detail in this chapter.
During system self-test, the yellow Fault light on the control panel lights.
If a module fails self-test, the Fault light remains lit. If all modules pass
self-test, the Fault light goes off.
Each CPU and memory module has a green LED that lights when the
module passes self-test. These LEDs can be viewed through the module
enclosure from the front and rear of the cabinet when the doors are open.
If a module fails self-test, its green LED does not light.
I/O modules have yellow LEDs that light when each module in the I/O card
cage passes self-test. These LEDs can be seen through the PIU enclosure.

Self-Test 2-3

2.2 Testing Sequence
The self-test display shows the results of system self-test. The pass
(+) or fail (−) status of each module is indicated.

During the first round of testing each module runs its own self-test and the
results are shown on the ST1 line. The boot processor is then determined
(indicated by a B on the first BPD line). This processor then generates the
results of testing to this point ( 1 ).
NOTE: If a processor fails self-test (ST1) in a multiprocessor system, there
is no indication of its failure in the self-test display. The failing
processor is logically disconnected from the backplane to prevent
faulty system operation. The processor failure is indicated by the
control panel Fault light remaining lit after power-up.
Next, the processors run a second round of tests using the memory modules. In this testing the processor that had been designated as boot processor could fail (as shown in Figure 2-2), so the boot processor is again determined. Results are displayed on the ST2 line ( 2 ).
Finally, the processors run a third round of tests, the multiprocessing
tests. Once again the boot processor is determined. The status of the boot
processor and secondary processors is then displayed on the third BPD line
( 3 ).
Results of the I/O adapter self-test are displayed next. The results are
shown in columns 1 through E, which stand for XMI node numbers.
The boot processor next configures memory and displays the configuration.
Note that it is the boot processor determined at ( 3 ) that displays the lines
after the third BPD line. The final line before the console prompt contains
the boot processor’s ROM revision and system serial number.
Each line of the self-test display is described in detail in the following sections of this chapter.

The NODE # line lists the node numbers on the LSB and XMI buses.
The nodes on this line are numbered in hexadecimal. Nodes 0 through
3 reflect the right-to-left position of the LSB slots as you view the LSB
from the front of the cabinet. Nodes 4 through 8 reflect the right-toleft position of the LSB slots as you view the LSB from the rear of the
cabinet.
Note that LSB entries use nodes 0 through 8, while the XMI has entries in nodes 1 through E. The LSB has 9 slots. The LSB slot numbers and node numbers are identical.
Each XMI bus has 14 slots. The XMI slot and node numbers are identical. Node numbers are 1 through E on the XMI.

The TYP line in the printout indicates the type of module at each LSB
node:
•

An adapter: the I/O port module (A)

•

A memory module (M)

•

A processor (P)

A period (.) indicates that the slot is not populated or that the module
is not reporting.

The ST1 line shows the results of self-test. This information is taken
from the self-test passed bit in the LCNR register of each module. The
entries are:
•

+ (pass)

•

o (does not apply)

NOTE: If a processor fails self-test (ST1) in a multiprocessor system,
there is no indication of its failure in the self-test display. The
failing processor is logically disconnected from the backplane
to prevent faulty system operation. The processor failure is indicated by the control panel Fault light remaining lit after
power-up.
Since the I/O port module does not have a module-resident self-test, its
entry for the ST1 line is always "o".
4

The BPD line indicates boot processor designation. When the system
goes through self-test, the processor with the lowest ID number that
passes self-test (ST1 line is +) becomes the boot processor, unless you
intervene.
The results on the BPD line indicate:
•

The boot processor (B)

•

Processors eligible to become the boot processor (E)

•

Processors ineligible to become the boot processor (D)

This BPD line is printed three times. After the first determination of
the boot processor, the processors go through two more rounds of testing. Since it is possible for a processor to pass self-test (at line ST1)
and fail ST2 or ST3 testing, the processors again determine the boot
processor following each round of tests.
In Figure 2-5 the processor at node 0 failed self-test, so the processor at
node 1 was chosen boot processor.
5

During the second round of testing (ST2) all processors run additional
CPU tests involving memory. In Figure 2-5 results printed on the ST2
line indicate that the processor at node 0 failed ST2 (−), while the processor at node 1 passed ST2 (+).
During the third round of testing (ST3) all processors run multiprocessor tests, and the status of each processor is once again reported on the
BPD line. The primary CPU also tests the IOP module at this time.

Self-Test 2-11

2.6 Self-Test Lines C0, C1, C2, and C3
The I/O channel lines (C0, C1, C2, and C3) of the self-test display
provide information on the node numbers and self-test status for
modules in the XMI card cages, which are connected to the system
bus through the IOP module and the DWLMA adapter.

The system configuration being tested is discussed in Section 2.3. See Table 2-1.
The I/O channel lines, C0 through C3, indicate the:
•

I/O channel that connects the XMI I/O bus to the system bus

•

DWLMA adapter self-test results

•

XMI adapters’ self-test results
7

In Figure 2-6 the DWLMA adapter accessed through C0 failed (−)
self-test (C0 XMI −).
The other DWLMA adapter was accessed through C1 and passed (+)
self-test (C1 XMI +); however, one XMI adapter, node 3, failed its selftest.
I/O channels C2 ( 9 ) and C3 ( 10 ) are not used in this system configuration.
When a DWLMA adapter passes self-test, each node on that XMI is indicated by symbols + and −, indicating the self-test status for that node
number on the XMI. A period (.) indicates that that node number is
not used. When a DWLMA adapter fails self-test, the failure is reported, and the XMI adapter self-tests are not displayed.
NOTE: The XMI clock module, always node 7, is not reported in the
self-test display.
The show configuration command gives additional information on
XMI I/O subsystems and adapters (see Section 3-1).

The ILV line contains a memory interleave value (ILV) for each memory. The default memory configuration algorithm attempts to maximize memory interleaving; arrays on a single memory module are interleaved by default. In Figure 2-7, the memory module at node 7 is in
a two-way system interleave indicated by the first interleave set A. Information on memory interleaving can be obtained by entering a show
memory command:

In this example, there are two memory interleave sets designated by
the letters A and B. Note that there is no A2 designator on the ILV
line; the memory at node 4 provides on-board interleaving, and so supplies both the A0 memory word and the A2 memory word (which is not
reported on the ILV line). Also note that different size memory arrays
can be interleaved into a single set by "stacking" the smaller arrays to
interleave with their larger counterparts.
12

The line after the ILV line displays the size of each configured memory
module in the system and gives the total size of system memory. In
Figure 2-7 the total size is 128 Mbytes.

In Figure 2-8 the Firmware Rev information, reported by the primary
processor, indicates the version of the console firmware.
The SROM Rev information indicates the primary processor’s serial
ROM version. The serial ROM contains the first level of console, diagnostic, and bootstrap code. This code initializes the CPU programmable features and diagnoses any faults detected along the bootstrap path
and bootstrapping code execution out to the main console program
(the second level of console, diagnostic, and bootstrap code).
SYS SN gives the system serial number. The serial number of the system is stored in the EEPROM of each processor and also appears on
the cabinet.

Power System Indicators A-1

A.1 AC Input Box
The AC input box with circuit breaker is located in the upper left rear of
the cabinet (see Figure A-1). The AC input box accepts three-phase power;
the three leftmost indicators on the circuit breaker show the state of each
pole (one pole per phase). If an indicator is green, the pole is in the off position or tripped due to an overload. If an indicator is red, the pole is in
the on position and is not tripped.
The fourth rightmost indicator reflects the mechanical position of the circuit breaker. The indicator is red when the circuit breaker is in the on position and green when the circuit breaker is in the off position.
NOTE: The function of the poles and indicators differs on the 202V AC input box. If one pole trips, all poles will trip, including the fourth
pole. All indicators will be green in this condition.
